Senior Full Stack Engineer & AI Engineer Nils Digital
I design and develop production-grade full-stack and AI-powered applications using TypeScript, Python, React, Next.js, Node.js, NestJS, FastAPI, and Django. I build responsive frontend systems, backend services, asynchronous workflows, REST and GraphQL APIs, real-time communication, and third-party integrations.
I architect scalable multi-tenant SaaS and event-driven systems using microservices, RabbitMQ, Kafka, PostgreSQL, MongoDB, MySQL, Redis, Prisma, and Drizzle ORM. I deploy cloud-native workloads on AWS, Azure, and GCP using Docker, Kubernetes, Terraform, and CI/CD pipelines, while leading architecture decisions, code reviews, performance improvements, and technical mentoring.
I build LLM-powered capabilities with OpenAI APIs, RAG pipelines, embeddings, vector databases, LangChain, LangGraph, and agent-based workflows. I also implement OAuth 2.0, JWT, RBAC, and OWASP-aligned security practices.
